I am having problems NFS mounting Ultrix (3.0 and 4.0) file systems on AIX
3.1. The following message is produced even when the appropriate
permissions are granted on exported directories.
# mount rsphy1:/users /mnt
mount: server rsphy1 not responding: RPC: Authentication error; why =
Invalid client credential
nfsmnthelp: rsphy1: The file access permissions do not allow the specified
action.
mount: giving up on:
rsphy1:/users
The file access permissions do not allow the specified action.
I successfully mount between DECStations running Ultrix 3.0 and 4.0 and
also between RS6000/320s including jfs and cd-rom file systems.
I can also mount from AIX to Ultrix successfully, and both ways SUNOS-AIX
and SUNOS-Ultrix. Also Ultrix-Connection 1.3 on VMS will mount on Ultrix
and AIX.
Has anyone out there successfully mounted Ultrix to AIX - are there any
patches required/hacks to passwd & group files/whatever?
Local reps from both IBM and DEC have been unable to help so far.
Please post to "david@phys.anu.edu.au" if you can help.

The problem is in the type of ethernet packet in use. Your RS6000 is using Xerox Ethernet, whereas you Ultrix station is using IEEE 802.3. If you change your RS6000 to use IEEE 802.3 things will work. For some reason this doesn't show up in other protocols, and most of the mounting process actually goes okay. It's when the actual ..MOUNT.. request gets sent that the 6000 sends a short packet and gets turned down. I'm sorry that I can't tell you how to change your card's packet type. It has something to do with configuring for et0 instead of en0, although netstat still shows en0 (isn't life great?). -John P. Eisenmenger Dept of Electrical Engineering Duke University

[i wrote this several months ago before we allowed news to be posted. i am posting it now because others may be interested to know that our problem disappeared by simply reinstalling unix! in fact, i even have the automounter working flawlessly. (i must have done something different than the original installer.) however, i am still curious why our network was unreachable with the device et0 though. --bw] david@phys.anu.oz writes: >> # mount rsphy1:/users /mnt >> mount: server rsphy1 not responding: RPC: Authentication error; why = >> Invalid client credential ... jpe@egr.duke.edu (John P.
